When are you required to stop for a school bus?

You are required to stop for a school bus when its lights are flashing and the stop sign is extended. This rule is in place to ensure the safety of children who may be boarding or disembarking from the bus. The flashing lights are a clear signal to all drivers that they must halt their vehicles to prevent any potential accidents or injuries.

When the stop sign is extended, it indicates that children may be crossing the road or are near the bus, making it crucial for drivers to remain stationary until the bus driver deems it safe to proceed. This regulation helps to create a safe environment for schoolchildren who are particularly vulnerable in these scenarios.

The other choices do not align with the established rules regarding school buses. For instance, stopping only when children are present neglects the preventive nature of the flashing lights and stop sign, which are designed to anticipate those active situations. Similarly, being parked on the side of the road does not trigger the need for a stop, as the active signal indicating danger is absent. Lastly, other vehicles stopping does not relieve individual drivers from their responsibility to stop when the bus has activated its signals. Following these regulations helps maintain safety on the road for everyone, especially children.
